EDWARD POSSON, OF CHICAGO, ILLINOIS.

GRAIN-DOOR.

To all whomz't may concern:

Be it known that I, EDWARD PossoN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Grain-Doors, of whichthe following is a specification.

The principal object of my invention is to provide a new and improveddoor for box freight cars.

Another object of my invention is to provide a door for a box freightcar that shall serve the purpose of an ordinary out-side door and thatshall at the same time be adapted to close tightly so as to serve as agrain door.

Another object of my invention is to provide a sheet metal door for abox freight car that shall be rugged in use, and capable of closingtightly to retain grain in the car.

Another object of my invention is to provide a tightclosing door for afreight car with subsidiary openings through the door by which grain maybe introduced or with drawn while the door itself remains in closedposition.

Another object of my invention is to provide means for convenientlyopening and closing a sliding door for a box freightcar.

Still another object of my invention is to provide a door for a boxfreight car that shall be simple in construction, durable, convenient tooperate by unskilled workmen, and capable of closing tightly, so as'toretain grain in the car.

All these objects and various others will be made apparent in thefollowing specification and claims, taken in connection with theaccompanying drawings.

In order to disclose the principle of my invention I have shown aspecific embodiment thereof in the accompanying drawings together withcertain alternative modifications of details.

In these drawings-Figure 1 is a side elevation of a door constructed inaccordance with my invention. Figs. 2 and 3 are horizontal sections onthe lines 2 and 3 of Fig. 1. Fig: 4 is a perspective view of the doorsill and guide. Figs. 5 and 6 are sections thereof taken on the lines 5and 6 of Fig. 4. Figs. 7, 8, 9 and 10 are sections on the respectivelines 7, 8, 9 and 10 of Fig. 1. Figs. 11 and 12 are sections on therespective lines 11 and 12 of Fig. 10. Fig. 13 is an eleva-Specification of Letters Patent. Patented'July 15, 1913. Applicationfiled September 20, 1910.

tion on an enlarged scale of the lower right hand corner of the door, asviewed in Fig. 1. Figs. 14 and 15 are sections on the respective lines14 and 15 in Fig. 13. Fig. 16 is an elevation of a door embodying myinvention, but modified in some respects as compared with that form ofthe invention disclosed in Figs. 1 to 15. Figs. 17 and 18 are verticalsections on the respective lines 17 and 18 in Fig. 16. Fig. 19 is anelevation on an enlarged scale of the lower right-hand portion of thedoor, as viewed in Fig. 16. Fig. 20 is a horizontal section on the line20 in Fig. 16. Fig. 21 is a perspective view of a detail of Fig. 16.Figs. 22 and 23 are detail horizontal sections of a still furthermodified form in which my invention may be embodied.

Reference numeral 21 designates the side wall of a box freight carhaving the usual inside door openingv which is closed by my improveddoor 22. This door 22, as shown in Fig. 1, consists of sheet metalstrength ened by the vertical and transverse ribs 28 which are struckout in it by a die. The top edge 41 of this door 22 lies within a topguide comprising an inner plate .38 and an outer plate 25 spaced apartalong their lower edges and both secured to the car wall under the eavesby means of the bolts 40. The sheet metal plate or flashing 39 laps overthe guide plates 25 and 38 and under the facia board 37, thus preventingwater from running down inside of the door at its top.

The door sill is a plate 26, as shown in Fig. 4, which lies on thewoodenfloor 34 and has its outer edge 26 upturned. The lower edge of the door22 is designated 42 and this lies within the upturned lip 26.

The member which constitutes the door sill 26 extends with the sectionshown in Figs. 9, 11 and 12 clear across the lower part of the dooropening and s then extended approximately an equal distance far ther tothe right of the door opening, the section of this extended partbeing asshown in Fig. 6, that is, with a broad flange 26" turned up and boltedto the side wall of the car. This part of the member 26 constitutes achannel with upstandingflanges 26 and 26 and in the web of this channelis a series of equally spaced perforations 51, the purpose of which willbe explained presently.

A plate 33 is riveted along the lower edge are out of registry,

of the door and laps down on the outside of the upstanding lip 26; thusthe lower edge of the door 22 rests on the plate-sill 26 and theupstanding lip 26, coacting with the edge 42 and the plate 33, affordguiding means for the lower edge of the door 22.

The door post 29 (from which the door 22 recedes when opened) isreinforced by the iron member 31 which has the horizontal section shownin Fig. Its outer edge 31 ,is bent double, butspaced from the main part,so as to-form a socket to receive the edge 48 of the door 22. The otherside post 30 (the one past which the door moves when it is being openedor closed) is reinforced by the iron member 32 which has a backwardlyturned outer edge 32. The corresponding edge of the door 22 is formed asa hooked member 49 that engages the lip 32' when the door is closed, asshown in Fig. 3.

The upper part of the door .22 has a rectangular opening therethrough,the edges of which are struck outwardly, as indicated by the referencenumeral 22" in Fig. 8. The edges 22" of this rectangular opening in thedoor 22 are reinforced by guide plates 64 above and and 71 at the sidesspaced out a little to receive the lateral edges 65 and 66 of the slide23. The slide 23 is reinforced across its lower part by the angle iron67. Below this is attached a housing 69 within which is pivoted a hookeddog 68 adapted to engage the lower edge of the top-opening in the door22 when the slide 23 is closed, as shown in Fig. 8.

The guide plate 33, at the lower edge of the door 22, is spaced out alittle by means of the filler plate 43 and it projects up a little so asto form a guide for a sliding closure 24. This closure 24 comprises asheet metal plate with two. openings 22 therein. There are correspondingopenings in the door 22 in its lower part with which these openings 22are adapted to register. As viewed in Fig. 1, the sliding closure 24 isdisplaced to the right so that the openings but it will be obvious thehandle 72 the sliding closure 24 can be shifted to the left, thusbringing the openings in registry. The guide lips 44 retain the upperedgeof the sliding closure 24.

At the lower left-hand corner of the door 22, as viewed in Fig. 1, thereis a reinforcthat by means of ing casting 45 whose construction and mode.----toe 45 integral of application to the adjoining parts are madeapparent in Figs. 10, 11 and 12. A V therewith hooks under the edge ofthe door sill 26.

At the lower right-hand corner of the door 22, as viewed in Fig. -1, acast iron member or plate 57 is attached; this reinforces andstrengthens the door, and carries operating mechanism therefor. It alsohas will seize the a lip 57 which extends under the edge of the doorsill 26 similarly to the lip 45 on the casting 45.

The short shaft 52, journaled in the casting 57, carries a gear pinion50, whose teeth engage the holes 51 in the extended channel part of thesill 26. The outer end of the shaft 52 has its sides flattened toreceive a crank lever 53, the two parts being secured v )ivot pin 55.The shaft end of the crank lever 53 is beveled,

designated by the reference numeral 56, so that the handle end may beswung outwardly from the car. As shown in Figs. 13, 14 and 15, thishandle end of the lever 53 is swung in toward thecar. A hasp 54, pivotedon the staple 59, laps over the lever 53 and between the shoulders 58 onthe casting 57. The upper end of this hasp 54 has an eye that engagesthe tongue 60, and a sliding dog 61 engages a hole in the tongue 60, soas to lock the hasp 54 in this posi tion. The tongue 60 and the guidefor the sliding tongue 61 are carried by a plate 63 riveted to one endof the sliding closure 24 and this same plate 63 carries a pivoted dog62 which looks the sliding dog 61 in place.

A stop 27 is provided on the car wall 21 to prevent the door 22 frommoving beyond a fully opened position.

Assuming that the door is fully closed, as in Fig. 1, and that thecontents of the car consist of grain which it is desired to remove, thedog 62 will be swung aside, the sliding dog 61 raised, and the hasp-54swung out and down. Then the operator willseize the handle 72 and movethe sliding closure 24 to the left, so as to open the outlets in thelower part of the door 22. Thereupon, all the grain lying adjacent tothe door 22 will run out through these outlets, thus relieving the door22 from the pressure of the grain on its inner side. Then the operatorhandle end of the lever 53 it out a little about the pivot pin togetherby a transverse 1 and-swing Next clockwise direction which, by reason ofthe engagement of the gear. pinion 50- with the recesses 51, will slidethe whole door to the right. The remainder of the grain can then beremoved from the car by the usual methods. 4

.When it is desired to fill the car with grain, the dog 68 (Fig. 8) isunhooked, so as to permit the slide 23 to be lowered. Then the door 22is closed and the sliding closure 24 at the bottom is also closed. Thegrain is introduced through the opening in the upper part of the door 22and then the slide 23 raised and the dog 68 automatically looks it inclosed position, so that access can thereafter be gained to theinteriorhe will rotate this lever 53 in a of the car only by unlocking the hasp54 at 4 the door 22 is definitely and positively guided on the sill 26by means of the edge guide 42, the riveted lip 33, and the underreachinghooks 45 and 57'. The upper guides25 and 38 simply prevent the upperedge of the door from swinging in or out. The interlocking elements 48and 31, and 49 and 32' (Fig. 3) come into engagement only when the dooris closed and afford grain tight joints at the sides of the door. Thedisposition of the elements 33, 26 and 42 (Fig. 9) prevents the escapeof grain at the bottom of the door.

The door22 is simple and rugged in its mounting, no rollers or pulleysbeing employed. In opening and closing the door the principal frictionto be overcome is along the sill 26 for the weight of the door rests onthis sill. The door operating mechanism, shown in Figs. 13, 14 and 15,acts directly along the line of frictional resistance. By means of thehandle 53 a powerful leverage is obtained, so that a workman can readilyopen or close the door and also force the interlocking edges-31, 48 and32', 49 into close engagement or withdraw them'therefrom.

Locking the hasp 54 not only looks the door as a whole, but also looksthe sliding closure 24. 'lVhen the upper slide 23 is closed it can beunlocked only from the inside.

The door posts 29 and 30 are reinforced by the members 31 and 32. Thesemembers also protect them against injury by abrasion of articles passingthrough the doorways or otherwise.

Referring now to the modifications shown in Figs. 16 to 21, in this casethe door is a plane sheet of metal reinforced by the vertical edge angleirons 74 and 75 and the intermediate ones 77 and 78 joined across thetop and bottom by other similar angle irons 76 and 79. These angle irons76, 77 and 78 are spaced out a little from the door 73 by means offiller strips 81, 82 and 83, so as to afford guide channels for theedges of the slide 80 which is adapted to close the rectangular openingin the upper part of the door 73. This slide 80 has a reinforcing angleiron 84 across its lower edge to which are pivotally attached the endsof the bail 85 for which a locking device 86 is provided on the wall ofthe door 73. The casting 97 at the lower right-hand corner is similar tothat shown in Figs. 13, 14 and 15, but the gear pinion is on the lowerside of the silk-here designated 96, and the rack 95 is riveted to thelower face of this sill 96 and is engaged by said gear pinion 50. v

The general description of the mode of operation for the device of Figs.1 to 15 inclusive will make clear the manner in which the device ofFigs. 16 to 21 may be operated. The slide 80 can be raised or loweredthe side wall thereof, in

by means of the bail 85. The teeth of the rack 95 projecting downwardlydo not become clogged with debris.

In Figs. 22 and 23there are shown interlocking elements for the sideedges of the door which may be built up instead of. being formedintegrally, as. in Figs. 3 and 20. The member 31 has its edge 90, and afiller 91, and the flange 92 riveted together to receive the when thedoor is closing. The following edge of the door has riveted thereto afiller 93 and flange 94 which engage the member 32 when the door closes.

It will be seen that I have constructed a simpleand strong metal doorwhich is adapted to perform the ordinary function of a side door forafreight car, which closes so tightly along its bottom and side edgesthat it will retain grain within the car, which, engages the bottom andsides of the door opening so securely as to resist the outward thrust ofgrain within the car and which may be operated without difficulty by anyunskilled workman.
